Dahlia plant named ‘Fidahhyprobico’

ABSTRACT

A new and distinct cultivar of  Dahlia  plant named ‘Fidahhyprobico’, characterized by its upright, somewhat outwardly spreading and mounding plant habit; early and freely flowering habit; large inflorescences with light red and yellow bi-colored ray florets; and good postproduction longevity.

Botanical designation: Dahlia variabilis.

Cultivar denomination: ‘FIDAHHYPROBICO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahliaplant, botanically known as Dahlia variabilis and hereinafter referredto by the name ‘Fidahhyprobico’.

The new Dahlia plant is a product of a planned breeding programconducted by the Inventor in Hillegom, The Netherlands. The objective ofthe breeding program is to create new pot-type Dahlia plants that have afreely branching and flowering habit, attractive ray floret colorationand good postproduction longevity.

The new Dahlia plant originated from an open-pollination in Hillegom,The Netherlands of an unnamed selection of Dahlia variabilis, notpatented, as the female, or seed, parent with an unknown selection ofDahlia variabilis as the male, or pollen, parent. The new Dahlia plantwas discovered and selected by the Inventor as a single flowering plantfrom within the progeny of the stated open-pollination in a controlledenvironment in Hillegom, The Netherlands.

Asexual reproduction of the new Dahlia plant by cuttings in a controlledenvironment in Hillegom, The Netherlands since 2006 has shown that theunique features of this new Dahlia plant are stable and reproduced trueto type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensity,without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Fidahhyprobico’. These characteristicsin combination distinguish ‘Fidahhyprobico’ as a new and distinctcultivar of Dahlia plant:

-   -   1. Upright, somewhat outwardly spreading and mounding plant        habit.    -   2. Early and freely flowering habit.    -   3. Large inflorescences with light red and yellow bi-colored ray        florets.    -   4. Good postproduction longevity.

Compared to plants of the female parent selection, plants of the newDahlia differ primarily in ray floret coloration and plant shape.

Plants of the new Dahlia can be compared to plants of Dahlia‘Fidahhyppi’, disclosed in U.S. Plant Pat. No. 21,254. In side-by-sidecomparisons conducted in De Lier, The Netherlands, plants of the newDahlia differed primarily from plants of ‘Fidahhyppi’ in the followingcharacteristics:

-   -   1. Plants of the new Dahlia had smaller inflorescences than        plants of ‘Fidahhyppi’.    -   2. Plants of the new Dahlia and ‘Fidahhyppi’ differed in ray        floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Dahlia plant showing the colors as true as it is reasonably possibleto obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Dahlia plant. The photograph comprises a side perspective viewof a typical flowering plant of ‘Fidahhyprobico’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and the following observations andmeasurements describe plants grown during the autumn in 15-cm containersin a glass-covered greenhouse in De Lier, The Netherlands and underconditions and practices which approximate those generally used incommercial potted Dahlia production. During the production of theplants, day and night temperatures averaged 18° C. Plants were nineweeks old when the photograph and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
